Description Disconnection of current transformer secondary circuit is accompanied by the appearance on the terminals of its secondary winding high-voltage pulses which are dangerous for isolation of a current transformer, its secondary circuit equipment and attending personnel. In the paper analysis of operating modes of current transformers with open their secondary circuits is carried out. The comparative analysis of calculation results of amplitudes of voltage pulses on the open secondary winding terminals of current transformer type TLM-10 (ТЛМ-10), which have been obtained by using computer simulation of its emergency operating mode and analytical calculations, is carried out.
